摘要：潼南铜梁两地经济在20年间突飞猛进，城市建设、城乡一体化的推进加快，其工业、商业、城乡居民用气量也随之大幅增加，该地区天然气管网不能满足未来10年的需求，出现气田产量完全能够满足用户需求而天然气管道却不能将天然气按需送至终端用户。本文针对潼南铜梁地区天然气市场的管网情况，利用试算平衡法、成本分析法、网络最大流等方法，在对未来该地区天然气需求预测和现有供气管网输气能力调查的基础上，提出适合该地区的管网建设方案。

ABSTRACT: With the development of TongLiang and tongnan regional economy by leaps and bounds in 20 years,the urban construction and integration of urban and rural areas speeds up quickly ;Industrial gas use, business, urban and rural residents has been greatly increased.Appeared the contradiction between supply and demand of natural gas in the region.Aiming at the contradiction between supply and demand of natural gas market, using the method of the trial balance, cost analysis and method of the shortest path Network maximum flow, supply and demand gap and gas supply pipeline gas transmission capacity in the future based on data such as best pipe network construction scheme is put forward.
Key words: natural gas；Contradiction between supply and demand；Maximum Network Flow；Pipeline construction
